Ubuntu's AppArmor is configured to allow certain important programs to request a high priority (negative niceness), most notably PulseAudio. This prevents breaks in playing audio while your system is under heavy load. In summary, yes all applications start with a normal priority. However, in practice, many applications request a different priority immediately after launching.

If the risk of locking up the machine is considered too big to enable real-time scheduling, high-priority scheduling can be enabled instead (i.e. negative nice level). This can be enabled by passing --high-priority (see above) when starting PulseAudio and may also be enabled with the appropriate option in daemon.conf .

PulseAudio requires higher priority than other desktop programs mainly to avoid latency problems and get a skip-free audio playback. But the process that allows PulseAudio to have a higher priority is rather complex. To get this special priority, it uses the RealtimeKit (rtkit-daemon) process. This D-Bus service allows some user programs to use real-time scheduling and …

PulseAudio High CPU Usage. I've noticed that when playing games, PulseAudio uses a less than insignificant amount of CPU time and this doesn't seem to have any real valid reason. It's 0% when idle (as expected) but if a game is playing audio, it can be between 2 and 50%, depending on the game. Running Factorio for example causes Pulse to use 15 ...
